Just received a replacement chassis for my 2-6-0 Baldwin big hauler engine.  Unfortunately the lead truck wires are broken off the truck.  Can anyone tell me  the red-black wire positions when the arrow on the truck points forward?  Don't want to get it reversed and cause a short.   Have my soldering gun out and I am ready to attach.  (I should really send it back to Bachmann, but I think I can get it working.) Thanks.

Can you see to trace which wire comes from which side of the drive wheels?

If not, then use your volt-ohm meter (VOM) in continuity (resistance) mode to determine which wire goes to which side of the powered wheels. If you don't have a VOM, you might be able to borrow one, or you can get one at Harbor Freight for around $10. It will be handy for all manner of construction and repair projects.

Are you sure you've got the right problem? There's a wiring diagram for the Indy here,, and it doesn't show any connection to the pony truck.  Afraid I have converted mine to battery, and can't remember from personal experience.  The 4-6-0 Big Hauler has a pickup in the front 4 wheel bogie (wiring diagram here, and good advice on George Schreyer's site  Afraid I've never even handled the Spectum (old time) 2-6-0, and I can't see any documentation on line for it.

I am thinking you mean the 4-6-0, and not the 2-6-0.  This is not an elegant solution, but you could solder the wires on then try it, if it shorts out just put the arrow on the truck facing to the rear or resolder.  

Jerry's  way using the meter is the overall best way to solve almost every wiring related problem we face with our trains.  Recently Harbor Freight was putting out coupons which would give you a free multimeter with any purchase of another item.  Free is almost always good Grin

Cheers & Beers
